OTECTION
If you run the engine on your pres sure wash er for 3-5
min utes with out pressing the trig ger on the spray gun,
cir cu lat ing water in the pump can reach high tem per a tures. When the water reaches this tem per a ture, the
pump pro tec tor engages and cools the pump by dis charg ing the warm water onto the g round. This ther mal
de vice pre vents internal dam age to the pump.
CLEANING TIPS
Pre-rinse clean ing surface with fresh water. Place de ter gent suc tion tube di rect ly into clean ing solution and
ap ply to sur face at low pressure (for best re sults, limit
your work area to sec tions approximately 6’ square
and always ap ply de ter gent from bottom to top). Allow
de ter gent to re main on sur face 1-3 min utes. Do not al low de ter gent to dry on sur face. If sur face appears to
be drying, sim ply wet down sur face with fresh water. If
need ed, use brush to re move stub born dir t. Rinse at
high pres sure from top to bottom in an even sweep ing
mo tion keep ing the spray nozzle ap prox i mate ly 1’ from
cleaning sur face. Use over lap ping strokes as you clean
and rinse any sur face. F or best surface clean ing action
spray at a slight an gle.
Recommendations:
• Before cleaning any surface, an inconspicuous
area should be cleaned to test spray pattern and
dis tance for maximum cleaning results.
• If painted surfaces are peeling or chipping, use
ex treme caution as pressure washer may re move
the loose paint from the surface.
• Keep the spray nozzle a safe distance from the
sur face you plan to clean. High pressure wash a
small area, then check the surface for damage. If no
dam age is found, continue to pressure wash ing.
CAUTION - Never use:
• Bleach, chlorine and other corrosive chem i cals
• Liquids containing solvents (i.e., paint thinners,
gas o line, oils)
• Tri-sodium phosphate products
• Ammonia products
• Acid-based products
These chemicals will harm the machine and will dam age the surface being cleaned.
RINSING
It will take a few sec onds for the de ter gent to clear.
Apply safe ty latch to spray gun. Re move black soap

4. Cover the pressure w asher and store in a clean, dry
place that is well ventilated away from open fl ame
or sparks. NOTE: The use of a fuel additive, such
as STA-BIL®, or an equivalent, will minimize the
for mu la tion of fuel deposits during shortage. Such

tank of the engine, or to the gasolinee in a storage
con tain er.
After Extended Storage
CAUTION: Prior to restarting, thaw out any
pos si ble ice from pressure washer hos es,
spray gun or wand.
Engine Maintenance
During the winter months, rare atmosheric conditions
may develop which will cause an icing con di tion in the
car bu re tor. If this de vel ops, the engine may run rough,
lose power and may stall. This temporary condition can
be overcome by deflecting some of the hot air from the
en gine over the carburetor area. NOTE: Refer to the

MAINTENANCE AND SERVICE
Unloader V alves:
Unloader valves are preset and tested at the fac to ry
be fore shipping. Oc ca sion al adjustment of the unloader
may be nec es sary to main tain correct pressure. Call
your lo cal dealer for assistance.
Winterizing Procedure:
Damage due to freezing is not covered by w arranty . Ad here to the following cold weather pro ce dures when ev er
the wash er must be stored or operated out doors under
freez ing conditions.

99
During winter months, when tem per a tures drop below
32°F, protecting your machine against freezing is nec es sary . Store the machine in a heated room. If this is not
pos si ble then mix a 50/50 solution of anti-freeze/water
into a 5 gal lon buck et. Place a short section of garden
hose into the buck et and connect it to the ma chine.
El e vate the buck et and turn the pump on to si phon the
anti-freeze through the ma chine. If com pressed air is
available, an air fitting can be screwed into the inlet
con nec tor and, by injecting com pressed air, all water
will be blown out of the system.
High Limit Hot Water Thermostat:
For safety, each machine is equipped with a high limit
con trol switch. In the event that the temperature of the
water should exceed its operating temperature, the
high limit con trol will turn the burner off until the water
cools.
Pumps:
Use only SAE 30W non-detergent oil. Change oil after
the first 50 hours of use. Thereafter , change the oil ev ery
three months or at 500 hour intervals. Oil level should be
checked by using the dipstic k found on top of the pump
or the red dot visible through the oil gauge win dow. Oil
should be maintained at that level.
Cleaning of Coils:
In alkaline water areas, lime deposits can accumulate
rap id ly inside the coil pipes. This growth is increased by
the extreme heat build up in the coil. The best pre ven tion
for liming conditions is to use high quality cleaning de ter gents. In areas where alkaline water is an extreme
prob lem, pe ri od ic use of our Deliming Powder (part
#9-028008) will remove lime and other deposits bef ore
coil becomes plugged. (See Deliming Instructions for
use of Deliming Powder.)
Deliming Coils:
Periodic flushing of coils is recommended.
1. Fill a container or optional fl oat tank with 4 gallons
of wa ter, then add 1 lb. of deliming powder. Mix
thor ough ly.
2. Remove wand assembly from spray gun and put
spray gun into container . Secure the trigger on the
spray gun into the open position.
3. Attach a shor t section (3-5 ft.) of garden hose to
ma chine to siphon solution from an elevated con tain er. Turn pump switch on, allowing solution to
be pumped through coils back into the container.
So lu tion should be al lowed to circulate 2-4 hours.
4. After circulating solution fl ush entire system with
fresh water. Reinstall wand assembly to spray
gun.

F!"#$
Use clean fuel oil that is not contaminated with water
and debris. Replace fuel filter and dr ain tank ev ery 100
hours of operation.
Use No. 1 or No. 2 Heating Oil (ASTM D306) only.
NEVER use gasoline in your burner tank. Gasoline is
more com bus ti ble than fuel oil and a serious explosion could result. NEV ER use crankcase or waste oil
in your burner. Fuel unit mal func tion could result from
con tam i na tion.
Fuel Control System:
These machines utilize a fuel solenoid valve located
on the fuel pump to control the flow of fuel to the com bus tion cham ber. This solenoid valve , which is normally
closed, is ac ti vat ed by a flow switch when water is flow ing through it. When an operator releases the trigger on
the spray gun, the flow of w ater through the flow switch
stops, turning off the current to the fuel solenoid. The
solenoid then closes, shutting off the supply of fuel to
the combustion chamber . Controlling the flow of fuel in
this way allows for an in stan ta neous burn or no burn
situation, thereby eliminating high and low water tem per a tures, and combustion smoke nor mal ly associated
with machines incorporating a spray gun.
CAUTION: Periodic inspection is recommended to in sure that the fuel solenoid valve functions properly . This
can be done by operating the machine and checking to
see that when the trigger on the spray gun is in the off
po si tion, the burner is not firing.
Burner Nozzle:
Keep the tip free of surf ace deposits by wiping it with a
clean, solvent-saturated cloth, being careful not to plug
or enlarge the nozzle. For maximum efficiency, replace
the nozzle each season.
Beckett Burner Air Adjustment:
Machines are preset and performance tested at the
fac to ry - el e va tion 100 feet. A one-time initial correction
for your lo ca tion will pay off in economy, performance
and ex tend ed ser vice life. If a smoking or eye-burning
ex haust is being emit ted from the stack, two things
should be checked. First, check the fuel to be certain
that ker o sene or No. 1 home heating fuel is being used.
Next, check the air ad just ment on the burner.
T o adjust: Start machine and turn burner ON. Loosen
two locking screws found in the air shutter openings
(re fer to illustration below) and close air shutter until
black smoke appears from burner exhaust vent. Note
air band position. Ne xt, slowly open the air shutter until
white smoke just starts to appear. Turn air shutter half way back to the blac k smoke position pre viously noted.
Tighten locking screws.
If the desired position cannot be obtained using only
the air shutter, loc k the air shutter in as close a position
